The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if this fault occurs.The Stop & Start system requires a
12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
The engine automatically restarts as soon as
the driver indicates the intention of moving off
again.

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation tips

Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level of
charge in the battery.
After switching off the engine and for a
maximum
cumulative period of around 40
minutes, you can
continue to use functions such as the audio and
telematics system, the wipers, the dipped beam
headlamps, the courtesy lamps, etc.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.
If a
telephone call is being made at this
time, it will be maintained for around
10
minutes with the Bluetooth hands-free
system of your audio system.
Exiting the mode
These functions will be automatically
reactivated the next time the vehicle is used.
In order to restore the use of these functions
immediately, start the engine and let it run:

Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a
CITROËN dealer or a qualified
workshop.
Cabin filter
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessar y .A clogged cabin filter may have an
adverse effect on the per formance of
the air conditioning system and generate
undesirable odours.

Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections

Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with
household waste.
Take used remote control batteries and
vehicle batteries to a
special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a
well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.

As the battery's negative terminal is not
accessible, a remote earth point is placed near
the battery.
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or using a
battery booster.
For access to the (+) terminal:
F

u
nlock the bonnet by activating the internal
release lever, then the external safety catch.
F
r
aise the bonnet.
Never start the engine by connecting
a battery charger.
Never use a 24 V or higher battery
b o o s t e r.
Check beforehand that the backup
battery has a nominal voltage of 12 V and
a capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
Switch off all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to the moving parts of the engine
(fan, belt, etc.).

Charging the battery using
a battery charger
For optimum ser vice life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
-

u
sing the vehicle mainly for short journeys,
-

i
f the vehicle is to be taken off the road for
several weeks.
Contact a
CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself,
use only a


charger compatible with lead-
acid batteries with a
nominal voltage of
12


V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery. F

S
witch off the ignition.
F
S
witch off all electrical consumers (audio
system, lighting, wipers, etc.). Never try to charge a frozen battery – risk
of explosion!
If the battery has frozen, have it checked
by a CITROËN dealer or by a qualified
workshop who will verify that the internal
components have not been damaged
and that the case has not cracked, which
would mean a
risk of toxic and corrosive
acid leaking.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Disconnecting the battery
F Switch off charger B before connecting the cables to the battery, so as to avoid any
dangerous sparks.
F

E
nsure that the charger cables are in good
condition.
F

I
f the vehicle has one, lift the plastic cover
on the (+) terminal.
F

C
onnect the cables of charger B as follows:
-

t
he positive (+) red cable to the (+)
terminal of battery A ,
-

t
he negative (-) black cable to earth point
C on the vehicle.
F

A
t the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A . In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of ser vice for a
long
period.
Before disconnecting the battery:
F

c
lose all openings (doors, tailgate, windows,
sunroof),
F

s
witch off all electrical consumers (audio
system, wipers, lighting, etc.),
